| Planet (or Dwarf Planet) | Distance from the Sun (Astronomical Units miles km) | Number of Moons |
|---|---|---|
| Mercury | 0.39 AU, 36 million miles 57.9 million km | 0 |
| Venus | 0.723 AU 67.2 million miles 108.2 million km | 0 |

Are Mercury and Venus close to each other?
Even though Mercury and Venus appear close together on the sky’s dome, they are not truly close together in space. At present, Mercury is more than three times Venus’ distance from Earth. Astronomers often measure solar system objects in terms of the astronomical unit (one Earth-sun distance).
Which is closer Mercury or Venus?
In other words, Mercury is closer to Earth, on average, than Venus is because it orbits the Sun more closely. Further, Mercury is the closest neighbor, on average, to each of the other seven planets in the solar system.
Why doesn’t Mercury have any moons?
Mercury and Venus Neither of them has a moon. Because Mercury is so close to the Sun and its gravity, it wouldn’t be able to hold on to its own moon. Any moon would most likely crash into Mercury or maybe go into orbit around the Sun and eventually get pulled into it.
How is Mercury different from Venus?
Venus and Mercury are the two planets that orbit closest to the Sun. Mercury is more dense than Venus and thought to consist of 60-70% metal, with the rest rock. As mentioned above, Mercury lacks an atmosphere, while Venus has the thickest atmosphere of all the terrestrial planets.
Is Mercury ever closer to Earth than Venus?
Although Venus is the planet that comes closest to Earth as it sweeps by on its orbit, Mercury stays the closest to Earth the longest, according to a commentary published Tuesday (March 12) in the magazine Physics Today.
Why is Venus the hottest planet instead of Mercury?
The carbon dioxide traps most of the heat from the Sun. The cloud layers also act as a blanket. The result is a “runaway greenhouse effect” that has caused the planet’s temperature to soar to 465°C, hot enough to melt lead. This means that Venus is even hotter than Mercury.
Who is the Earth closest planet?
It’s Mercury! Of all the planets in the Solar System, Mercury has the smallest orbit. So although it never gets quite as close to the Earth as Venus or Mars, it never gets far away from us also! In fact, Mercury is the closest – for most of the time- planet not only to the Earth, but also to Mars and Venus and…
